General description

Benzophenone is an organic compound that can be prepared by the atmospheric oxidation of diphenyl methane with copper naphthenate catalyst. It can also be synthesized by the Friedel-Crafts acylation of benzene with benzoyl chloride.

Application

Benzophenone is mainly used as a photoinitiator molecule in a variety of 3D printing applications. It has a high quantum yield that makes it useful in the development of UV curable photopolymers.
